WW1	the tank, heavy artillery, chemical warfare, radio comms, the combat airplane, aerial surveillance and aerial bombing
WWII	the A Bomb and nuclear power, jet propulsion, computers, mobile warfare, rocketry, communications intercept and cryptography, the submarine snorkel, carrier-borne air-power, carpet bombing, radar (in all its forms), ASW sonar, amphibious operations, ECM and jamming
Korea	napalm, psy-warfare, jet-fighter tactics, United Nations, limited warfare
the Cold War (and Cuban Missile Crisis)	the moon landings as a winner in the Space Race (JFK: We will put man on the moon in this decade and return him safely to earth..."), NBC warfare (nuclear, chemical and biological), ICBM's, economic blockade the end of the Cold War - the Soviets folded when Reagan's Star Wars Technology seemed to them to be insuperable and made their mutual common denominator of Mutually Assured Destruction (MAD) a vestige of the past.
Vietnam	the helicopter (combat assault and medevac), battle-field PGM's (precision guided munitions), large-scale defoliation, SLAR, remote sensor surveillance, anti-radiation missilery (HARM), infra-red surveillance, ESM (electronic sensor measures), frequency-hopping radios, TFR (terrain following radar), Wild Weasel
The Gulf War	real-time satellite surveillance, unmannned drone (RPV) surveillance, precision laser-guided bombing and GPS-directed cruise missiles, CBU's, night vision goggles, secure comms, ABM defence (against MRBM SCUD missilry), Stealth, air supremacy, air-defence suppression, DU munitions, CB warfare, discrete targeting
The Balkan Wars -	RPV link-directed artillery and laser-designation, selective destruction (of oil-refineries and buildings), satellite imagery location of mass graves, humane war against civilian populations, effective decoying, employment failures of sophisticated technology (Apache)
The Terrorist Wars - ?	hallowed martyrdom (istishard),
And of course you could give credit to the Israelis	for RPV's (Bekaa Valley and Syrian Campaigns), the non-use (but deterrent possession) of nuclear weapons and their own "targeted" anti-terrorist tactics and intelligence skills. Counter-terror targeting of prominent figures in particular.

So don't doubt that this is where we are heading with this one - into the world of necessity being always the Mother of Invention. The fanatical sleeper suicide-terrorist is one of the greatest technological challenges one might ever dream up....worse even than those prolific Communist cells of the 1950's. Because of where the M.E. terrorists come from, I doubt that you can ever drain the swamp (as Donald Rumsfeld has been saying) - the problem with fanatics is that they are queuing up for their assured place in paradise - and as time goes by in this forthcoming war, they will multiply exponentially. General Gordon of Khartoum was always fearful of the advent of the Mahdi, because of his effect upon the Muslim horde's fighting spirit. When the Mahdi came, as if out of his dreams, and led those savage Muslim hordes to victory and Gordon to a terrible death, well it was if the Mahdi had never been but at the same time had ever been. The Muslim hordes knew that the Mahdi would come and lead them. That there was a Mahdi was simply a self-fulfilling prophecy that stemmed from their beliefs. In that bin Laden is rapidly taking on the dimensions of a latter-day Mahdi, it's now like waiting for the Messiah and hoping he can defeat the anti-Christ. In order to understand the motivation and mind-set of the M.E. Terrorist you first have to study the Quranic historicity of it all.
